  • Rare-earth element - Processing ores Britannica

    All rare-earth ores contain less than 10 percent REO and must be upgraded to about 60 percent in order to be processed further. They are first ground to a powder and then separated from the other materials in the ore body by various standard processes that include magnetic and/or electrostatic separation and flotation.

    Separation Pilot PlantService CapabilitiesExpertiseIn addition to bench and pilot testing, SRC has built a separation pilot plant that can be configured to different separation processes for either group separation or individual REE separation. SRC adapted that technology to address specific REE separation challenges in processing secondary rare earth resources, such as uranium raffinate. Our technology is also applicable to separating concentrates from primary rare earth mineral resources, such as monazite and bastn
